parsing error: identifier 'reacttypingeffect' has already been declared. in javascript

This error occurs when the same identifier is declared more than once in a scope in JavaScript. In this case, 'reacttypingeffect' is already declared somewhere in your code and you are declaring it again. To fix this error, you need to find the previous declaration of the identifier and remove or rename it.

Here's an example of how this issue can occur in React:


import React, { useState } from 'react';
import reacttypingeffect from 'react-typing-effect';

function MyComponent() {
  const [text, setText] = useState('Hello World!');

  // The following line defines the `reacttypingeffect` identifier
  const reacttypingeffect = () => {
    setText('Type Effect');
  };

  // The following line tries to import the `react-typing-effect` library
  // with the same identifier `reacttypingeffect`
  return (
    <div>
      <reacttypingeffect text={text} />
    </div>
  );
}

To fix this error, we need to choose a different identifier name for the function or library import. We could simply rename the function to a unique name like "myTypingEffect". Here's the updated code:


import React, { useState } from 'react';
import reacttypingeffect from 'react-typing-effect';

function MyComponent() {
  const [text, setText] = useState('Hello World!');

  // Renamed `reacttypingeffect` to `myTypingEffect`
  const myTypingEffect = () => {
    setText('Type Effect');
  };

  return (
    <div>
      <reacttypingeffect text={text} />
    </div>
  );
}

This should fix the issue and allow your code to compile without errors.
